Hearing screening is a program that must be performed to check for common neonatal conditions in order to detect congenital hearing disorders in newborns in a timely manner, and clinically hearing screening is passed at the latest at 6 months of age. Hearing screening is usually done at 3 days, 42 days, 3 months and at the latest at 6 months of age to check for auditory brainstem response potential, otoacoustic emissions, acoustic impedance, stapedial muscle reflexes, etc. to clarify whether the child has congenital deafness, inner ear malformations, otosclerosis and related disorders such as large vestibular duct edema syndrome. If the child does not pass the hearing screening at 6 months of age, he or she may be congenitally deaf and will need to be fitted with a hearing aid early for assistive listening and language development training. Normal hearing is a prerequisite for language learning. Infants and toddlers with normal hearing generally begin babbling at 4-9 months and no later than 11 months, while children with severe hearing impairment are unable to establish normal language learning during the most important and critical years of language development, 2-3 years of age, due to lack of language stimulation and environment. In mild cases, this leads to language and speech impairment, low social adjustment, attention deficit and learning difficulties, and other psychological and behavioral problems, while in severe cases the child leads to deafness. Therefore, if hearing screening reveals problems, early targeted treatment should be provided to avoid further development of the condition and its impact on the child’s future life.
